The Cessna 421 Golden Eagle is a development of the earlier Cessna 411 light, twin-engine personal transport aircraft. The main difference between the two models is that the 421 is pressurized.
The 421 was first produced in May 1967. The 421A appeared in 1968 and the aircraft was redesigned in 1970 and marketed as the 421B. In 1975 the 421C appeared which featured wet wings, the absence of wing tip fuel tanks and landing gear that was changed from straight-leg to a trailing-link design from the 1981 model year onwards. Production ended in 1985 after 1,901 aircraft had been delivered.
Note: Even though this model is designed using reference photos to get as close to accurate as possible, it is not strictly accurate.
